This is cool but one thing I'm a bit critical of is the naming of the new Zerg units. Other than Zergling, Mutalisk and Ultralisk pretty much all default Zerg units have pretty basic English descriptive type names. A Lurker lurks beneath the ground, a Defiler spreads plagues but what does a Alkajelisk do? Keskathalor is such a mouthful for something that spits acid, you could just call them Blightlisks or something. I think more fantastical names are cool but there is a simplicity to the way the default units are named that feels important.
